Conventionally, yes, but presumably these researchers have figured out the correct parameters for formulation, grain size and electron beam energy to flash melt and refreeze the alloy quickly enough to avoid crystallization of both old and new layers. If they haven’t, then this tech is not very useful at all. As it is, while additive manufacturing has some very significant advantages over injection molding, 3D-printed BMG would have fewer advantages over the many other metals available to that process. Much of the novelty of amorphous alloy is the compatibility with injection molding and hot forming, all of which facilitates minimal post-processing, corrosion resistance and mold-ready surface finishes.
